Answer

Brief Explanations:

  1. Henry Moseley arranged elements by atomic number, which is correct.
  2. Atomic mass generally increases from left - to - right on the periodic table, not decreases.
  3. Atomic number increases from left - to - right as new protons are added, which is correct.
  4. Metalloids create a "staircase" down the periodic table, not nonmetals.
  5. Metalloids have properties of both metals and nonmetals, which is correct.

Answer:

Henry Moseley established a periodic table that arranges the elements by atomic number., The atomic number increases from left to right on the periodic table., Metalloids have the characteristics of both metals and nonmetals.
